Having errors when opening pdf’s
Hello,
This iPad’s version is IOS 12.0.1, Adobe Acrobat app’s version is 18.10.01 (20181022.151200).
When I open a pdf file on google drive and add some comments on it, I can no longer open it again with error message as below after I close it.

And when I open the same pdf file in Files, I can’t read it either as below.

I can’t even click into my “drive” to see other files in it as below.

Acrobat showed me errors many times after I tried editing several different pdf’s. Hope that anyone can help me.
Thanks
